Exactly. The issue that Davies is talking about is that of the infringement of civil liberties on a wide scale. Personally, I think that's serious stuff. For a senior politician to say that it's time to draw a line - that's an interesting development, at the very least.
And it's not simply about attacking Labour. Just as importantly, it's an attempt to commit the Tories to calling a halt to the drift towards authoritarianism.
Davies has previously said that a Tory government would abandon the ID card scheme and would repeal the 42 days. This is his attempt to secure those policies.
I'd be more impressed with those dismissing the entire thing if they were offering a better way of opposing the attacks on civil liberties. Or - in the absence of any action - could even point to someone else who's doing so.
